Missing privileges, for system actions, without consolekit

[Thanatermesis]

Seems like when autologin is set, the user logins with less privileges, so all the system actions are grayed out (reboot/shutdown/suspend/hibernate)

autologin should use the same login system as a normal user (since its the mode that works correctly) also to maintain compatibility between modes and not turning in future bugs or hard to catch ones
